The chosen IDLH, therefore, has been estimated from the statement by Baskin [1975] that severe symptoms follow swallowing or skin contamination with 15 to 50 mg/kg (average adult). According to Deichmann [1973], aldrin vapor gave no effect in man at 18 mg/m3 during exposure for 1 day.. Short-term exposure guidelines: None developed. ...
On December 12, 2017, Pennsylvanias Environmental Quality Board (EQB) unanimously approved a final-omitted rulemaking to substantially increase the Act 2 cleanup standards for beryllium, cadmium, and aldrin. The Act 2 cleanup standards are risk-based, meaning they are calculated according to the methods described in 25 Pa. Code Chapter 250 using the best-available toxicological data to be protective of human health under a variety of exposure scenarios. The standards must be periodically revised as newer and more accurate toxicological information becomes available, and the last such revision occurred in August 2016.. This currently proposed revision is intended to correct errors that were discovered in the 2016 cleanup standards for three substances: aldrin, beryllium, and cadmium. The original and corrected cleanup standards are presented in the table below.. ...
The Diels-Alder reaction of hexachlorocyclopentadiene with norbornadiene givesaldrin but theoretically three other diastereofacial isomers are possible. On oxidation theseisomers can generate eight adducts one of which is known as dieldrin. All these, as well asthe corresponding reactions with hexafluorocyclopenadiene were studied by semiempirical(AM1 and PM3) and hybrid density functional (B3LYP) methods. Besides the energy levels,the transition states were calculated for the reactions leading to the diastereofacial isomers ofaldrin, which indicate that aldrin is the favored product of the reaction both fromthermodynamic and kinetic point of view.

Christ says no man knoweth the day or the hour when the Son of Man cometh. This is a sweeping argument for sectarianism against Latter day ism. Did Christ speak this as a general principle throughout all generations Oh no he spoke in the present tense no man that was then liveing upon the footstool of God knew the day or the hour But he did not say that there was no man throughout all generations that should not know the day or the hour. No for this would be in flat contradiction with other scripture for the prophet says that God will do nothing but what he will reveal unto his Servants the prophets consequently if it is not made known to the Prophets it will not come to pass; again we find Paul 1st of Thesslonians 5th Chapter expressly points out the characters who shall not know the day nor the hour when the Son of Man cometh for says he it will come upon them as the theif or unawares. Who are they they are the children of darkness or night. But to the Saints he says yea are not of the night ...
Aldrin joined him on the moons surface at 11:11 p.m., and together they took photographs of the terrain, planted a U.S. flag, ran a few simple scientific tests, and spoke with President Richard M. Nixon via Houston. By 1:11 a.m. on July 21, both astronauts were back in the lunar module and the hatch was closed. The two men slept that night on the surface of the moon, and at 1:54 p.m. the Eagle began its ascent back to the command module. Among the items left on the surface of the moon was a plaque that read: "Here men from the planet Earth first set foot on the moon-July 1969 A.D-We came in peace for all mankind." At 5:35 p.m., Armstrong and Aldrin successfully docked and rejoined Collins, and at 12:56 a.m. on July 22nd, Apollo 11 began its journey home, safely splashing down in the Pacific Ocean at 12:51 p.m. on July 24. ...

In other actions, EPA has concluded a Six-Year Review of 69 Drinking Water Regulations and has finalized regulatory determinations for nine contaminants on the Contaminant Candidate List. For both of these decisions, EPAs review included the best available data on health effects, analytical methods, treatment technologies, and occurrence. For the Six-Year Review, EPA has concluded that the monitoring requirements for Total Coliform (an indicator of bacterial contamination of drinking water) should be revised. EPA also finalized determinations on nine contaminants and found that at this time it is not appropriate to develop regulations for Acanthamoeba, Aldrin, Dieldrin, Hexachlorobutadiene, Manganese, Metribuzin, Naphthalene, Sodium, and Sulfate.

Our ADA mission aboard Aquarius allowed us to tour the exterior of the structure and supporting equipment outside, then enter the habitat from the underside, where we climbed stairs into the pressurized environment. Once inside we took off our dive gear, had warm showers, and changed into street clothes to experience the living and working facilities where moon-walking astronaut Buzz Aldrin has trained. Only about 1,600 divers have ever dove an Aquarius mission in the past 24 years, and the experience was unique. The full story and pictures of our ADA mission can be seen in the archives of this newsletter, in the July, 2016 edition.. Those of us who were lucky enough to have participated in last years Aquarius mission decided that we should work on a program for ADA to support FIUs work through the facility. So the ADA board approved a proposal to fund two partial scholarships for FIU students studying marine sciences involving Aquarius: one graduate level and one undergraduate. We are now ...
Armstrongs family released a statement describing him as a "reluctant American hero [who had] served his nation proudly, as a navy fighter pilot, test pilot, and astronaut ... While we mourn the loss of a very good man, we also celebrate his remarkable life and hope that it serves as an example to young people around the world to work hard to make their dreams come true, to be willing to explore and push the limits, and to selflessly serve a cause greater than themselves. For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink."[217] It prompted many responses, including the Twitter hashtag "#WinkAtTheMoon".[218] Buzz Aldrin called Armstrong "a true American hero and the best pilot I ever knew", and said he was disappointed that they would not be able to celebrate the 50th ...

ABSTRACT. Organochlorine pesticide (OCPs) residues were monitored in muscle samples of Lates calcarifer, Liza subviridis and Cynoglossus cynoglossus collected during October-December (Dry season) 1996 and May-July (Wet season) 1997 from the Ganges estuary. The OCP residues were analysed by Gas-Chromatography (GC) in Electron Capture Detector (ECD) mode and were verified by Thin Layer Chromatography (TLC). OCP residues were more in the muscles of Lates calcarifer because of its carnivorous characteristic, and lowest in Liza subviridis, a herbivorous fish. The OCP residue concentrations were found in order of heptachlor,dieldrin,DDTs,aldrin for Lates calcarifer and in order of DDTs,heptachlor,dieldrin,aldrin for the Cynoglossus cynoglossus. In Liza subviridis only DDTs were found. A good positive linear correlation was observed between the pesticide residues ( DDT and OCPs) and lipid contents of fishes. Among the nine OCP residues analysed only dieldrin and heptachlor residues in Lates calcarifer ...

Here, we provide compelling evidence that exposure to a long-day photoperiod switches the polarity of GABAergic activity in most SCN neurons from inhibitory to excitatory. Presynaptically, sPSC frequency changes with differing day lengths, whereas postsynaptically, the photoperiod affects GABAergic activity within the SCN by changing the equilibrium potential of GABA-evoked current. The increase in excitatory GABAergic activity was reduced after blocking the Cl− cotransporter NKCC1 using bumetanide, suggesting a modulation of NKCC1 activity or expression. Thus, our data show that environmental conditions affect GABAergic activity by modulating cellular properties on a basic biophysical level.. The key mechanisms that contribute to the degree of synchronization within the SCN, reflected in the photoperiodic-induced changes in phase distribution (3), may depend on the ratio of excitatory to inhibitory GABAergic activity within the SCN, rather than an overall increase in GABAergic tone. The role ...

The situation analysis report found out that Zimbabwe faces significant and growing resistance in common infections such as TB, malaria, HIV, respiratory infections, sexually transmitted infections (STIs), urinary tract infections (UTIs), meningitis and diarrheal diseases. Even with the latest typhoid outbreak that took place in the country, the people experienced 22% resistance to ciprofloxacin.. One major driver of resistance is the increased antimicrobial consumption in both humans and animals. However the data on antimicrobial use and patterns of AMR in humans and animals in Zimbabwe are limited.. In Zimbabwe there is also lack of meaningful surveillance data to help understand resistance patterns, prevalent organisms and guide policy development.. In his speech on behalf of his superior, Aldrin Masiyiwa the Deputy Minister of Health and Child Care said AMR was declared a world health threat at the 68th World Health Assembly in 2015 whereby countries were urged to put in place National ...
Years of watching General Hospital, and recent months of All My Children, have made the word betray, and all of its forms, my second most loathed word in the English language (first: moist, much like Lily Aldrin; third: Babe), so when Zach opened up his truth-telling tour with: Zach: You betrayed me. You broke my trust, you broke my heart. I cant let it go. I involuntarily rolled my eyes, snorted and groaned, which was quite nearly tragic, as I was drinking water at the time. I could have died! This is the second time this week that AMC has nearly put me in physical peril, in addition to mental anguish. Watching this show is hazardous to my health! Its not that I am opposed to Kendall and Zach airing their grievances and honestly, openly discussing the ways theyve hurt each other. I think thats necessary in order for them to have anything approaching a normal relationship. Or at least as normal as a relationship can be when the male partner is keeping the female partner locked away in a secret

Taking the 266 nm excited pyrimidine (uracil or thymine) with cyclopentene as model reaction systems, we have examined the photoproduct formation dynamics from the [2 + 2] photocycloaddition reactions of triplet pyrimidines in solution and provided mechanistic insights into this important DNA photodamage reaction. By combining two compliment methods of nanosecond time-resolved transient IR and UV-vis laser flash-photolysis spectroscopy, the photoproduct formation dynamics as well as the triplet quenching kinetics are measured. Characteristic IR absorption bands due to photoproduct formation have been observed and product quantum yields are determined to be similar to 0.91% for uracil and similar to 0.41% for thymine. Compared to the measured large quenching rate constants of triplet uracil (1.5 x 10(9) M(-1)s(-1)) or thymine (0.6 x 10(9) M(-1)s(-1)) by cyclopentene, the inefficiency in formation of photoproducts indicates competitive physical quenching processes may exist on the route leading to ...

But the Green Revolution he inspired has left behind a toxic legacy. In order to support the new breeds of plants produced, the agricultural industry produced hundreds of thousands of tons of pesticides a year through the 1950s, 60s, and onward. Unfortunately, it turned out that many of these pesticides contained/contain toxins and persistent organic pollutants. Things like lindane, aldrin, dieldrin, chlordane, heptachlor, and DDT - carcinogens, endocrine disruptors, bioaccumulators.. While, to the international societys credit, we did manage to ban the production and use of many of these chemicals through instruments like the Stockholm Convention, we are left with tens of thousands of tons of these compounds, idling in sometimes poorly stored containers worldwide. Africa alone has 50,000 tons of these now obsolete pesticides, which have occasionally been unintentionally released into communities by leaks and poor disposal practices.. ...
The study was to investigate the impacts on the ecosystem health in relation to levels and distribution of organochlorine pesticides that have either been banned or restricted for use in Kenya. The pesticides targeted were DDT, lindane, aldrin, dieldrin, heptachlor, endrin, endosuphan, and methoxychlor. Prior to their ban or restriction in use, they had found wide applications in public health and agriculture for control of disease vectors and crop pests respectively.. A study was conducted in which 880 samples of soil, water, sediments, aquatic weeds and benthic macroinvertebrates were collected from 26 locations representative of the River Nyando drainage basin catchment area of 3450 km2 and a total length of 170 km of the Lake Victoria Catchment over a period of two years. Soils from six farms were sampled in areas where maize, tea, sugar cane, col fee, rice and vegetables have been grown over the years. The objective was to investigate the impacts on the ecosystem health in relation to ...

Religious observations are even tougher in a real spacecraft. Launch weight limitations forced Buzz Aldrin to pack a "tiny Host" and thimble-sized wine chalice for his DIY Communion on the moon. Zero gravity and a ninety minute orbital day created so many questions for Muslim astronauts that a "Guideline of Performing Ibadah at the International Space Station" was drafted. Rather than require Muslim astronauts to pray five times during each ninety minute orbit of Earth, the guidelines allowed them to go by the twenty-four-hour cycle of the launch location. Wipes ("not less than 3 pieces") could be used for preprayer cleansing. And since the orbiting Muslim who began his prayer while facing Mecca was likely, by prayers end, to be mooning Mecca, provisions were made allowing him to simply face the Earth or "wherever."

What good is a museum collection of bird eggs? In the case of peregrine falcons, egg collections helped save the species.. After World War II new organochlorine insecticides were introduced on the open market and widely used in agriculture. Some of them, such as seed dressings of dieldrin, aldrin and heptachlor, instantly killed birds as they fed in the fields. DDT was more insidious.. By the mid 1960s, seed dressings were already banned in Britain but the peregrine population was still crashing and Derek Ratcliffe wondered if something else was going on. Since 1951 he and other peregrine monitors had seen many broken eggs in eyries and frequent nest failure. Ratcliffe wondered if peregrine eggs were collapsing because the eggshells were thin. He decided to find out.. Egg collections are empty shells (notice the tiny drill hole in each specimen above). You must not break them to measure the shells thickness. However the weight of the shell correlates to thickness if you account for the size of ...

To many NASA observers, it may seem self evident that the Mars Rovers are a shining icon of our engineering prowess that all of humanity can be proud of, in the same way as we are proud of the achievements of Neil Armstrong and Buzz Aldrin. But scientifically and technically, what is the main aim of these missions? I would argue that the chief objective of the NASA Mars Exploration Program is to open human hearts to the Martian frontier and focus the efforts of our best and brightest minds on the goal of exploring the nearest inhabitable planet in our Universe.. For example, SpaceX was founded in 2002, in the midst of the excitement of the 2003 MER missions, Spirit and Opportunity. If these rovers had been cancelled or failed to launch, would Elon Musk and his 1,800 employees, some of the nations best and brightest, be around today working on spacecraft and launch vehicles that could one day take us to Mars?. A second example is relevant: if the Mars Exploration program is discontinued or ...
In this study a number of cage alkenes were synthesised and tested for activity towards ringopening metathesis polymerisation (ROMP) with the commercially available catalysts 55 (Grubbs-I) and 56 (Grubbs-II). The first group of monomers are derivatives of tetracyclo[6.3.0.04,1105,9]undec-2-en-6-one (1). The synthesis of these cage alkenes are summarised in Scheme 7.1. The cage alkene 126b was synthesised by a Diels-Alder reaction between 1 and hexachlorocyclopentadiene (9, Scheme 7.2). The geometry of 126b was determined from XRD data. Knowledge of the geometry of 126b also established the geometry of 127 since conformational changes during the conversion from 126b to 127 are unlikely. Synthesis of the cage alkene 125 by the cycloaddition of 9 to 118 failed. The cage alkene exo-11-hydroxy-4,5,6,7,16,16-hexachlorohexacyclo[7.6.1.03,8.02,13.010,14]hexa-dec-5-ene (124, Scheme 7.3) could therefore not be prepared. Synthesis of 125 by reduction of 126b with various reduction systems was not ...
In an evaluation of carbon nanotubes (CNTs) for the IARC Monograph 111, the Mechanisms Subgroup was tasked with assessing the strength of evidence on the potential carcinogenicity of CNTs in humans. The mechanistic evidence was considered to be not strong enough to alter the evaluations based on the animal data. In this paper, we provide an extended, in-depth examination of the in vivo and in vitro experimental studies according to current hypotheses on the carcinogenicity of inhaled particles and fibers. We cite additional studies of CNTs that were not available at the time of the IARC meeting in October 2014, and extend our evaluation to include carbon nanofibers (CNFs). Finally, we identify key data gaps and suggest research needs to reduce uncertainty. The focus of this review is on the cancer risk to workers exposed to airborne CNT or CNF during the production and use of these materials. The findings of this review, in general, affirm those of the original evaluation on the inadequate or ...
